I realized that you don't need a hex base to built on au contaire they restrict the placement of contours and have to be one hex size apart.if you prefer historical scenarios its restrictive in replicating accurate table.Basically you need 4 types of hexesthe more gradual slope hexes are a cast version

Great to see the hex terrain. It always supprises me more folke don't do modular terrain. I must confess we do use a hex base. Original we did not an in some ways it is better. However if you need detailed reproduceable maps then an underlying hex grid is very usefull. We like you still do not use hex based roads and rivers. It lacks the smooth countours and belivability that show for instance in your terrain.
